Problems solved by technology

However, the capacitive touch screen cannot directly sense the strength of the touch, and can only sense the click of the skin, but cannot sense the click of fingernails, gloved fingers or other objects, so the operation is still inconvenient
At present, the above problems are mainly solved by the sensor group distributed under the touch screen, but it has several major disadvantages: 1. The sensor can only sense the force near it, so it is necessary to set up more sensors to form a group to cover the entire touch screen, so that Adds weight, complexity and power consumption to the device
2. There are several layers of glass between the sensor and the finger touch. The energy of the finger touch can only be sensed by the sensor after being dispersed and attenuated by the glass. Therefore, the accuracy is not high, and it is difficult to accurately give the force of the touch

Embodiment Construction

[0038] In the present invention, more than four sensors need to be dispersedly arranged under the sensing panel of the touch device. The sensor senses a touch at any position on the panel, receives the shock wave signal generated by the touch, and then analyzes the received shock wave signal to determine the touch position and obtain the touch energy, thereby providing a basis for quantifying the touch.

[0039] The present invention will be described in detail below by taking a touch control device with a touch screen as an example and referring to the accompanying drawings.

[0040] Such as figure 1 As shown, in Embodiment 1, four sensors are dispersedly arranged on the sensing panel of the touch device, that is, the touch screen, and their positions are respectively expressed as (x 1 ,y 1 ), (x 2 ,y 2 ), (x 3 ,y 3 ), (x 4 ,y 4 ). When a human finger or other object touches a point on the touch screen, a shock wave will be generated at the touch point (x, y). The s...

Abstract

The invention relates to a bunting position and energy measurement method based on a wave propagation time and energy function. According to the method, a plurality of sensors are arranged below a touch equipment perception panel so as to response a blast wave signal generated by bunting; blast wave signal energy and arrival time therefore are detected; according to a principle that the blast wave group velocity is similarly equal in each direction on the aspects of isotropic or quasi-isotropic structure, the bunting position is analyzed and calculated; and according to the relationship that the bunting dynamics and the blast wave signal energy are in direct proportion, the blunting energy is analyzed and calculated. According to the bunting position and energy measurement method based on the wave propagation time and energy function, which is disclosed by the invention, the method in the prior art that a group sensor, such as an array sensor, needs to be arranged to sense the bunting dynamics is changed, and the amount of required sensors is reduced so as to reduce the total weight, the complexity and the energy consumption of the touch equipment, and the cost is greatly lowered. The bunting position and energy measurement method based on the wave propagation time and energy function can be used for electronic equipment with a propagation panel, such as a touch screen, a game control panel and a shooting target, and performs the functions of assisting or replacing the traditional positioning method based on the technology, such as resistance and capacitance.

Description

technical field [0001] The invention relates to a method for monitoring the position and energy of a touch, in particular to a method for measuring the position and energy of a touch based on wave propagation time and energy functions for a touch device. Background technique [0002] Because of its simple and fast operation, touch devices have become the preferred configuration of current human-computer interaction electronic products. They can be seen everywhere from industry to home, from office to entertainment. While pursuing accuracy, stability, convenience and speed, people put forward more expectations and requirements, such as further enhancing the sensitivity of force sensing, reducing weight, and reducing energy consumption. [0003] Taking electronic products with touch screens as an example, most mainstream technologies on the market currently use capacitive touch screens. However, the capacitive touch screen cannot directly sense the strength of the touch, and ...
